TECHNICAL FIELD

The present invention relates to a woven and knitted fabric subjected tomold processing. In particular, the present invention relates to a wovenand knitted fabric having imparted thereto satisfactory moldprocessability through use of heat-fusible polyurethane elasticfilaments.

BACKGROUND ART

There is known an approach to imparting mold processability to a wovenfabric or a knitted fabric by providing the fabric with thermoplasticfibers. JP 2001-98446 A (Patent Literature 1) discloses a technology formold processing, involving using polyurethane elastic filaments eachhaving a high heat setting rate. JP 2006-225817 A (Patent Literature 2)discloses a technology for mold processing, involving using polyurethaneelastic filaments and nylon fibers.

However, it cannot be said that any of the technologies is sufficient inactual mold processability. In addition, according to such technology,the mold processing is performed by applying excessive heat, and hencethermoplastic fibers of a face yarn harden. As a result, the wovenfabric or knitted fabric to be obtained is poor in fabric feeling andtakes on a shine in some cases.

In the technology described in Patent Literature 2, it is assumed that,when a woven and knitted fabric containing elastic fibers (polyurethaneelastic filaments) is subjected to the mold processing, synthetic fibers(e.g. nylon or polyester) having high thermoplasticity are mixed andused in the face yarn and the processing is performed at hightemperature. The reason for this is to set the synthetic fibers mixedand used at a certain rate by heat, thereby reducing a shrinking forceof the polyurethane elastic filaments. When such high-temperatureprocessing is assumed, it is substantially impossible to subject afabric mainly containing natural fibers or regenerated fibers having nothermoplasticity to the mold processing.

Further, in the case of the high-temperature processing as describedabove, when a fabric after dyeing processing is subjected to the moldprocessing, heat at the time of the mold processing causes a dye tosublime. Hence, a color of the processed part changes and fastness isdeteriorated in many cases. Thus, there is provided only a producthaving low commercial product performance. In addition, in the case ofthe high-temperature processing, the fabric undergoes yellowing owing tothe heat, and hence the processing cannot be employed for light-coloredfabric. Therefore, only part of the fabric subjected to the moldprocessing may be cut out and used, but it is impossible to subject onlya desired part of the fabric as a whole to molding and then use thewhole as a product.

In addition, in the case where a fabric mainly containing the naturalfibers or the regenerated fibers and containing no polyurethane elasticfilaments is subjected to the mold processing, it is necessary to applyheat at 200° C. or more. This results in yellowing of the natural fibersor the regenerated fibers. On the other hand, when the polyurethaneelastic filaments are used in combination with the natural fibers or theregenerated fibers, elasticity of the polyurethane causes shrinkage.Hence, it is practically impossible to subject a fabric using thenatural fibers or the regenerated fibers and the polyurethane elasticfilaments to the mold processing.

JP 2008-138298 A (Patent Literature 3) discloses a technology for moldprocessing, involving using a yarn that is excellent in low-temperaturesetting property. Although this yarn provides excellent formability froma low temperature region, a proper range of a processing temperature isnarrow. Therefore, there are many limitations in a dyeing processingstep in preparation of a base fabric to be subjected to the moldprocessing and fibers usable therewith are limited. In addition, when aheat treatment temperature, the mold processing temperature, or the likeis shifted to high temperatures in the preparation of the base fabric,there arises a problem in that breakage of the polyurethane elasticfilaments occurs, for example. Owing to the breakage of the polyurethaneelastic filaments, a fabric after forming is liable to lose shape, hasno stretching property, and is inferior in appearance as well.

The applicant of the present application has proposed a technologyinvolving using heat-fusible polyurethane elastic filaments in a wovenand knitted fabric containing polyurethane elastic filaments, therebytrying to achieve heat setting property, misalignment prevention, andthe like (Patent Literatures 4 and 5). However, this technology achievesonly misalignment prevention and fray prevention.

DESCRIPTION OF EMBODIMENTS

Hereinafter, the present invention is described in more detail.

A woven and knitted fabric of the present invention includes a yarncontaining elastic fibers and at least one kind of non-elastic fibers,the woven and knitted fabric being subjected to mold processing. Theelastic fibers contain heat-fusible polyurethane elastic filaments eachhaving a fineness of 17 dtex or more, and at least part of theheat-fusible polyurethane elastic filaments is heat-fused in the wovenand knitted fabric. The woven and knitted fabric is subjected to themold processing at 120 to 190° C.

As the elastic fibers, elastic fibers well known in the art may be used.The elastic fibers are preferably polyurethane elastic filaments. As thepolyurethane elastic filaments, polyurethane elastic filaments wellknown in the art may be used.

The heat-fusible polyurethane elastic filaments to be used in thepresent invention are not particularly limited as to their composition,production method, and the like as long as the heat-fusible polyurethaneelastic filaments are polyurethane elastic filaments having suchheat-fusion property as to allow the filaments at crossover pointstherebetween to be heat-fused each other.

The heat-fusible polyurethane elastic filaments may be obtained by, forexample: (1) a method involving allowing a polyol to react with anexcess molar amount of a diisocyanate to produce a polyurethaneintermediate polymer having isocyanate groups at both ends, allowing theintermediate polymer to react with a low-molecular-weight diamine orlow-molecular-weight diol having active hydrogen capable of easilyreacting with the isocyanate groups of the intermediate polymer in aninert organic solvent to produce a polyurethane solution (polymersolution), and then removing the solvent to form the solution into astring; (2) a method involving solidifying a polymer obtained through areaction among a polyol, a diisocyanate, and a low-molecular-weightdiamine or a low-molecular-weight diol, dissolving the solidifiedpolymer in a solvent, and then removing the solvent to form the solutioninto a string; (3) a method involving forming the solidified polymerinto a string by heating without dissolving the polymer in a solvent;(4) a method involving allowing the polyol, the diisocyanate, and thelow-molecular-weight diol to react with each other to produce a polymer,and forming the polymer into a string without solidifying the polymer;or (5) a method involving mixing the polymer or polymer solutionobtained in each of the methods, and then removing the solvent from amixed polymer solution to form the mixed polymer solution into a string.

The heat-fusible polyurethane elastic filaments may be preferablyobtained by a method involving melt spinning the following polymer. Thepolymer is obtained by allowing a prepolymer (A) having isocyanategroups at both ends, which is obtained through a reaction between apolyol and a diisocyanate, to react with a prepolymer (B) havinghydroxyl groups at both ends, which is obtained through a reaction amonga polyol, a diisocyanate, and a low-molecular-weight diol. This methodis suitable from an economic or environmental viewpoint as well becausethe method does not involve recovering a solvent.

In addition, a composition including 50 mass % or more of a polyetherpolyol in the polyol component in the raw materials is preferablyadopted. With such composition, a polymer excellent in alkali resistancecan be obtained, and hence limitations on conditions for the dyeingprocessing of fibers to be used in combination can be reduced.

With regard to the heat-fusion performance of each of the heat-fusiblepolyurethane elastic filaments to be used in the present invention, aheat-fusion force is preferably 0.15 cN/dtex or more, and morepreferably 0.30 cN/dtex or more. If the heat-fusion force is less than0.15 cN/dtex, satisfactory mold processability may not be obtained.

For example, in the case of a knitted fabric, the heat-fusion force ismeasured in the following manner.

The knitted fabric is cut in a course direction, and an unravelingtension is measured for heat-fusible polyurethane elastic filaments or ayarn containing heat-fusible polyurethane elastic filaments, the fibersor yarn being knitted within the cut portion. An unraveling speed is setat 100 mm/min, and an average unraveling tension during a period of 1minute is measured. When continuous unraveling is possible, averageunraveling tensions are measured before and after heat treatment. Then,the average unraveling tension (cN) after the heat treatment is dividedby the initial fineness (dtex) of the heat-fusible polyurethane elasticfilaments to determine the heat-fusion force (cN/dtex). It should benoted that the heat-fusion force is so strong in some cases that theunraveling of the heat-fusible polyurethane elastic filaments isdifficult. The heat-fusion force in those cases, which is needless tosay 0.15 cN/dtex or more, is judged as “complete fusion.”

The fineness of each of the heat-fusible polyurethane elastic filamentsto be used in the present invention is, from the viewpoint of the fabricfeeling of the woven and knitted fabric to be obtained, preferably 17dtex or more, more preferably 22 to 311 dtex, still more preferably 28to 156 dtex. If the polyurethane elastic filaments are thinner than 17dtex, the area of a part to be heat-fused (i.e., a heat-fusion area),which is a crossover point between the polyurethane elastic filaments incontact with each other, decreases. As a result, the setting property ofthe fabric decreases, and hence desired moldability may be difficult toobtain. An upper limit for the fineness is not particularly limited.However, when the fineness of the fibers is large, the fabric becomeslike rubber, and hence there is such a general tendency that fibershaving small fineness are preferred.

As the heat-fusible polyurethane elastic filaments to be used in thepresent invention, a yarn formed of only the heat-fusible polyurethaneelastic filaments (bare yarn) may be adopted, or a composite yarn suchas a covered yarn (a single covered yarn or a double covered yarn), adouble twist yarn, or an air interlaced yarn may be adopted. Of those, acovered yarn is preferred because the heat-fusible polyurethane elasticfilaments may be placed at the center of the composite yarn, and thecoverage of the heat-fusible polyurethane elastic filaments can beeasily controlled and uniform covering can be achieved.

When the composite yarn (e.g., covered yarn) is used as the heat-fusiblepolyurethane elastic filaments, non-elastic fibers for covering theheat-fusible polyurethane elastic filaments are not particularlylimited. As such non-elastic fibers, there may be used, for example:natural fibers such as cotton, hemp, wool, and silk; regenerated fiberssuch as rayon, cupra, and polynosic; semi-regenerated fibers such as anacetate; and chemical synthetic fibers such as nylon, polyester, acryl,and polypropylene.

In the woven and knitted fabric of the present invention, as describedabove, the elastic fibers in the fabric are preferably polyurethaneelastic filaments. In addition, the mixture ratio of the polyurethaneelastic filaments in the fabric is preferably 5% or more, morepreferably 8% or more, and still more preferably 10% or more. An upperlimit for the mixture ratio of the polyurethane elastic filaments ispreferably 35%, and more preferably 25%. In addition, the mixture ratioof the heat-fusible polyurethane elastic filaments in the polyurethaneelastic filaments is preferably 50% or more, more preferably 80% ormore, and still more preferably 100%. When the mixture ratio of theheat-fusible polyurethane elastic filaments falls within such range, aheat-fusion area between the polyurethane elastic filaments can beincreased to provide a fabric having higher formability.

As the non-elastic fibers for constituting the woven and knitted fabricof the present invention, non-elastic fibers well known in the art maybe used. Specific examples of the non-elastic fibers include thosedescribed above for the case where a composite yarn is used asheat-fusible polyurethane elastic filaments.

The woven and knitted fabric subjected to mold processing of the presentinvention is produced in substantially the following manner.

First, at least one kind of the non-elastic fibers and the elasticfibers containing a bare yarn of the heat-fusible polyurethane elasticfilaments or a composite yarn containing the heat-fusible polyurethaneelastic filaments are prepared. The elastic fibers and the non-elasticfibers are used to provide a woven and knitted fabric through weaving,knitting, or the like. The fabric then is subjected to heat setting orheat treatment of mold processing, thereby heat-fusing at least parts ofthe heat-fusible polyurethane elastic filaments with each other.

The woven and knitted fabric of the present invention may be constructedof a woven fabric or a knitted fabric depending on its applications. Forexample, when the woven and knitted fabric of the present invention isconstructed of the woven fabric, any one of plain weaving, twillweaving, satin weaving, and the like may be employed. Further, when theknitted fabric is used, a well-known knitting method such as warpknitting or weft knitting may be appropriately employed.

For example, when the woven and knitted fabric of the present inventionis constructed of the knitted fabric, a knitted fabric obtained byplating knitting the heat-fusible polyurethane elastic filaments and atleast one kind of non-elastic fibers is preferred. The knitted fabricobtained by the plating knitting allows the heat-fusible polyurethaneelastic filaments to be stably heat-fused with each other at a crossoverpoint of knit stitches at the time of heat treatment, and thus the knitstitches can be fixed.

As a weft knitted fabric to be used in the present invention, plainknitting, rib knitting, double knitting, or the like may beappropriately employed. Plain knitting is preferred because a fabric isfinished into a thin product and the fabric undergoes no significantchange in shape of each of a needle loop and a sinker loop even when thefabric is partially stretched in molding.

The draft rate of the heat-fusible polyurethane elastic filaments at thetime of the weaving or knitting of the fabric is preferably 1.0 to 3.6times, and more preferably 2.0 to 3.0 times.

Next, the fabric is processed through general steps. For example, aseries of processing steps “refinement-bleaching-presetting-dyeing-finalsetting” is performed. Then, the processed fabric is subjected to moldprocessing. The mold processing is preferably performed at a temperatureof 120 to 190° C. Through the mold processing at such temperature, thewoven and knitted fabric of the present invention subjected to the moldprocessing after dyeing processing may have a color change resistancegrade of Grade 3 or more. If the temperature is less than 120° C.,formability may be insufficient. If the temperature is 190° C. or more,a face yarn undergoes yellowing or hardening, and hence the fabric maynot clear the color change resistance grade. It should be noted that thecolor change resistance grade may be determined according to JIS L0804.

Treatment of the mold processing is typically performed as follows.Further, a forming rate is calculated as follows.

A spherical jig made of iron (diameter: 105 mm, weight: 1.5 kg) as amold processing jig is heated with a dryer to a given processingtemperature. When the temperature of the jig becomes stable, the jig ispressed against a fabric, which is unstretched and left to stand still,for 1 minute to form the fabric. In this case, the jig is caused to sinkby 70 mm. After having been left to stand still at ordinary temperaturefor 30 minutes, the depth of a depression in the fabric is measured, andthe ratio of the measured value to the depth at the time of the forming,i.e., 70 mm is calculated, which is defined as the forming rate.

The forming rate of the woven and knitted fabric of the presentinvention is preferably 20% or more, more preferably 25% or more, andstill more preferably 30% or more. The combination of such forming rate(mold processability) and the excellent color change resistance grade isone of the achievements of the present invention.

As evident from Tables 1 and 2, it can be understood that each exampleof the present invention is excellent in both forming rate and colorchange resistance grade. Comparative Examples 1 and 2 were inferior informability, and Comparative Examples 4 and 5 were inferior in colorchange resistance. Comparative Example 3 was satisfactory informability, but breakage of polyurethane elastic filaments occurred. Asalso evident from Tables 1 and 2, according to the present invention,mold processability can be imparted to even a fabric containing naturalfibers or regenerated fibers having no thermoplasticity, and even awoven and knitted fabric containing thermoplastic fibers having low heatresistance, such as nylon or polypropylene, does not show yellowingafter processing with the result that a light-colored fabric can also besubjected to mold processing. As a result, satisfactory formability canbe imparted to a product required to have shape-maintaining property,such as underwear such as a cup portion of a brassiere, or a hip portionof shorts or a girdle, a knitted fabric for indoor sports such asswimming wear, or a woven fabric for outerwear such as a bottom, and thedesigning of the product can be performed freely. In particular, theface yarn free of hardening provides good fabric feeling of the fabricand the use of the natural fibers or the regenerated fibers causes noskin disorder such as rash even upon direct contact with a delicateportion of skin. In addition to the field of clothing, a wide range ofapplications are possible, such as a combination with another materialto provide a laminate material having stretching property.
